Happy New Year to everyone out there.

Causing reasonable excitement among us editors this morning is the new journal metric/citation analysis website SCImago. Finally, an alternative to Thomson’s Impact Factors.

SCImago not only offers h-indices for journals, but also a new indicator all of their own: the SCImago Journal Rank (SJR) indicator (read the maths here). They’ve apparently developed this from Google’s all-powerful PageRank algorithm. In addition to measuring the average number of citations to papers a journal publishes, it also weights those citations – citations from a higher SJR-ranked journal are worth more than those from a lower-ranked journal.

Another benefit is that the data comes from Elsevier’s Scopus database, which in my experience is somewhat more comprehensive and accurate than Web of Knowledge.

And finally, the whole thing is freely availabe. Which is nice.

I’ve had great fun working out which metric gives the journals I work on the highest placing on the list – now you can choose from SJR, h-index, papers published, citations per paper, etc, etc.

Tieing in nicely with the article in this January’s print Chemistry World (How good is UK chemistry?, pp 42–23), you can also use the data to analyse a country’s performance. The data pretty much reflects what Evidence Ltd found from their analysis of Thomson’s data.
